There are still crashes as of the 1.14.1 update. I really wish it was fixed so everyone on our realm could play again like normal.
This has been affecting players in our worlds for weeks now. Ever since the foxes were added to the game. I admit it does seem like it's chunks loading because of course everyone wants to see and get the newest mobs in the game. Sometimes the game will say the world is corrupted and other times it will just kick us all out without any warning. It happens in my own worlds too, sometimes my whole screen freezes and I can't move and I have to restart the game. Sometimes I can load back in just fine, but other times any dogs, cats, horses, or birds that were with me just disappear like I never had them.
This affects me as well. Sometimes I can load into Minecraft and the graphics for the inventory, especially enchanted items, are very grainy and broken. Within 15 minutes or so Minecraft lags and then freezes. Then my computer does to the point I have to manually shut it off by holding the power button. This happens on realms as well as my own private world. Everything else on my laptop is working normally.
